7703897 U ( 32) Filed 10 Feb 1977 in ( 33) Fed Rep of Germany (DE) ( 44) Complete Specification published 3 Sept 1981 ( 51) INT CL 2 B 32 B 5/26 ( 52) Index at acceptance B 5 N 0526 ( 72) Inventor MANFRED KRULL HOLGER BUCHWALD WILHELM KIRSCH ( 54) WOUND COMPRESSES ( 71) We, CARL FREUDENBERG, a German Company (a Kommanditgesellschaft, the present personally responsible partners of which are HELMUT FABRICIUS, HANS ERICH FREUDENBERG, OTTO SCHILDHAUER, HERMANN FREUDENBERG, DIETER FREUDENBERG, and REINHART FREUDENBERG), of 6940 Weinheim Bergstrasse, Hohnerweg 2, West Germany, do hereby declare the invention, for which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in and by the following statement:-
The present invention relates to wound compresses which do not cohere with a wound, have good absorption of wound secretion, yet deter complete penetration of wound secretion.
Numerous wound compresses based upon fabrics or fleeces are known which use textile fibres or threads of natural substances, for example cellulose, possibly with a small proportion of synthetic fibres Natural substances have an extraordinarily good absorption effect but they very rapidly cohere with the wound After the wound secretion has dried, more or les great difficulties arise in removal of the wound compress In many cases healing is prevented by the repeated tearing open of the wound For this reason it has already ben proposed that one of the outer layers of the wound compress be formed of synthetic materials, such as polyesters or polyolefines However, it has appeared that such wound compresses encourage dispersion of wound secretion, which vary rapidly pentrates to the other outer layer Unfortunately, when a wound compress is wet through there is an increased danger of external infection, germs from the atmosphere experiencing more difficulty in reaching a wound through dry covering material.
According to the present invention, however, a wound compress comprises at least five superimposed layers, the two outer layers being formed of a material which is permeable to secretion from a wound but does not cohere with the wound, and the inner layers including two or more absorbent layers, formed primarily of cellulose fibres, which are separated from one another by one or more distributor layers formed of cellulose, carboxy methyl cellu 55 lose or starch.
Due to the provision of the or each distributor layer a greater effectiveness is achieved in that wound secretion is spread out horizontally Thus, not only that 60 material lying directly over the wound is used in absorption Only in the event that a relatively large area is saturated does wound secretion penetrate to the exposed outer layer of the wound compress Con 65 sequently the danger of external infection is eliminated or at least substantially reduced.
A preferred wound compress according to the present invention consists of five layers, 70 that is to say two outer layers, two absorbent layers and a single centrally located distributor layer, the symmetry of the wound compress enabling either of its outer layers to be applied to a wound with equal effec 75 tiveness.
The or each of the distributor layers, which as mentioned above is formed of cellulose, carboxy methyl cellulose or starch, is preferably formed as tissue wad 80 ding, a fleece or a fabric.
Each of the outer layers, which as mentioned above is formed of a material permeable to wound secretion without cohering with the wound, is preferably formed as a 85 knitted or woven fabric, a fleece or a perforated synthetic plastics foil Said fleece or said fabric of the outer layers may contain fibres or filaments of polypropylene, polyethylene, polyesters and/or polyamides 90 Moreover, each of the outer layers may have had a polyolefine powder sintered thereon.
The preferred synthetic materials for the outer layers present smooth surfaces which are much more compatible with skin than 95 conventional muslin textiles However, the smooth surfaced synthetic materials can be structured in a manner which avoids undesirable slipping of the wound compress.
The structuring advantageously includes air 100 Ch CI 1 596891 passages which not only promote permeability but also promote healing.
At least one of the outer layers may be provided with areas of a skin-compatible self-adhering adhesive This eases the task of applying the wound compress and is especially preferable for smaller wounds.
Alternatively, the wound compress may be secured in position by a separate adhesive plaster or a separate muslin bandage.
To avoid any protrusion of broken fibres, especially from the inner layers, the edges of the wound compress are preferably secured to one another by adhesive, and to avoid contamination prior to use the entire wound compress is preferably located within a removable paper container.
Claims (6)
1 A wound compress comprising at least five superimposed layers, the two outer layers being formed of a material which is permeable to secretion from a wound but does not cohere with the wound, and the inner layers including two or more absorbent layers, formed primarily of cellulose fibres, which are separated from one another by one or more distributor layers formed of cellulose, carboxy methyl cellulose or starch.
2 A wound compress according to claim 30 1, in which the or each of the distributor layers is formed as tissue wadding, a fleece or a fabric.
3 A wound compress according to claim 1 or claim 2, in which each of the outer 35 layers is formed as a knitted or woven fabric, a fleece or a perforated synthetic plastics foil.
4 A wound compress according to claim 3, in which said fleece or said fabric con 40 tains fibres or filaments of polypropylene, polyethylene, polyesters and/or polyamides.
A wound compress according to claim 3 or claim 4, in which a polyolefine powder has been sintered on to each of the outer 45 layers.
6 A wound compress according to any preceding claim, in which at least one of the outer layers is provided with areas of a skin-compatible self-adhering adhesive 50 7 A wound compress according to claim 1 and substantially as hereinbefore described.
